CVT lifespan

Hi everyone,

I have a 2012 Nissan versa which uses a CVT. I am close to hitting 100k miles and just had my transmission serviced. I'm not having any problems with the transmission, but just wanted to do routine maintenance on my car. When I was at the shop, the guy kept telling me how unreliable CVTs are and I'm lucky I got 100k miles out of it. He also made it sound like it could totally fail at any point in the near future. So I'm just curious how long do CVTs last? He said they typically fail around 70k miles. If they truly don't last much longer than 100k miles then maybe I should look into getting a new car while mine is still working. I tried looking it up online but I don't trust the AI content.

Thanks!
